Definitions
- the present invention generally relates to speakers and more particularly to ceiling speakers.
- suspended ceilings having acoustical ceiling panels have been developed to absorb and abate extraneous noise within a confined space.
- the modular design of such panels allows for ease of installation and ease in office space reconfiguration. Building planners often specify modular ceiling panels as a standard system within their designs. Ceiling panels can both enhance the work environment by providing acoustic sound absorption and attenuation, and by providing a pleasant monolithic visual appearance. Thus, there has been an increased emphasis on specifying ceiling systems with high acoustic absorption and pleasant visual appearance.
- Loudspeakers often are used to provide sound in a workspace. Such sounds typically may include paging messages, music, and background masking which reduces the effect of unwanted noise from infrastructure systems such as ventilation systems, and mask speech noise allowing for greater speech privacy.
- Ceiling systems that are substantially monolithic in structure and design. Such ceiling systems provide a pleasant visual appearance to the person viewing the ceiling from below. Loudspeakers often are required in office spaces where ceilings are formed of ceiling panels. Preferably, the installation of loudspeaker systems within a suspended ceiling does not interrupt the desired monolithic design of the ceiling.
- loudspeaker systems for installation in suspended ceilings are unable to provide a modular design that can integrate both functionally and visually into the ceiling system.
- many speaker systems when installed, protrude below the plane of the ceiling panels, thus interrupting the planar surface of the ceiling.
- speaker systems can be installed by cutting out a portion of a panel and installing a speaker with a round perforated grill within the opening. Such a speaker grill clearly interrupts the monolithic appearance of the ceiling and is considered unsightly by some.
- the present invention provides a flat panel sound radiator assembly system that is substantially visually equivalent to the monolithic look of surrounding ceiling tiles in a suspended ceiling.
- the assembly is modular in design and provides an acoustic facing that is substantially visually indistinguishable from surrounding ceiling panels.
- the flat panel sound radiator assembly comprises a frame and a radiating panel resting within the frame.
- the frame includes a bridge element fitted to the frame.
- the radiating panel has both a backing and facing side and an acoustic transducer mounted to the backing side of the radiating panel.
- An acoustic facing concealing the facing side of the radiating panel is applied, wherein the acoustic facing is substantially visually indistinguishable from surrounding ceiling panels.
- the flat panel sound radiator assembly further comprises part of a monolithic suspended ceiling structure, wherein the assembly is virtually visually indistinguishable from the surrounding ceiling tiles of the suspended ceiling.
- a further embodiment of the present invention includes a ceiling system comprising a plurality of ceiling panels having an exposed surface and a flat panel sound radiator.
- the flat panel sound radiator comprises a support and an acoustical visually matched exposed layer.
- the exposed layer of the radiator is substantially visually indistinguishable from the exposed surfaces of the ceiling panels.
- the flat panel sound radiator assembly and system conceals the modular speaker so that it appears substantially the same as the ceiling panels that surround it. In this way, the monolithic appearance of the ceiling is not interrupted.
- FIG. 1 is an isometric view of the frame element and attached extrusion element
- FIG. 2 is a bottom view of the acoustic facing showing a rectangular frame, a partial view of the facing and exposed frame element;
- FIG. 3 is a bottom view of the facing side of the acoustical facing further illustrating the facing support members
- FIG. 4 is a cutaway side view of the flat panel sound radiator illustrating an acoustic facing applied directly to a radiating panel
- FIG. 5 is a cutaway side view of the flat panel sound radiator illustrating an acoustic surface applied as a pigmented coating to the radiating panel.
- the present invention generally relates to a modular flat panel sound radiator assembly for installation in a suspended ceiling that is compatible with and virtually visually indistinguishable from surrounding ceiling tiles of the ceiling system.
- the modular flat panel sound radiator comprises a ceiling assembly sized to fit within a ceiling support grid and preferably within the same plane as the surrounding ceiling tiles.
- the flat panel sound radiator assembly comprises a substantially indistinguishable part of the monolithic ceiling tile system.
- the flat panel sound radiator assembly includes a frame resting within the ceiling support grid and a radiating panel set within the frame.
- a bridge element is added to the frame to support a portion of the electrical components that are operatively connected to the backing side of the radiating panel.
- An acoustic facing is added to conceal the facing side of the radiating panel, and the acoustic facing is substantially visually indistinguishable from the surrounding ceiling panels.
- a ceiling system comprising a flat panel sound radiator that is substantially indistinguishable from the surrounding ceiling panels.
- the flat panel radiator is more fully described in a co-pending and commonly assigned U.S. Patent Application entitled, “Flat Panel Radiator and Assembly System” having U.S. patent application No. 09/627,706 which is incorporated by reference as though set forth in fall herein.
- the ceiling system essentially comprises a plurality of ceiling panels each having an exposed surface of a substantially similar pattern as the other ceiling panels.
- the system comprises an acoustical radiator having a support and an acoustically transparent and visually matched exposed layer.
- the visually matched exposed layer is substantially indistinguishable from the exposed surfaces of surrounding ceiling panels so that the ceiling appearance remains significantly monolithic in both structure and design.
- the system integrates both functionally and visually the acoustical radiator into the ceiling system.
- the frame 300 is illustrated in FIG. 1 as being rectangular, which is the standard shape of most grid openings in a ceiling panel system. While the frame 300 is shown as rectangular, the frame 300 may take any shape so long as it fits within the grid of a suspended ceiling.
- the frame 300 is fitted within the standard grid opening of a ceiling system so that the flat panel sound radiator can easily be installed and, when installed, forms part of the monolithic structure of the ceiling system.
- the frame 300 is sized to fit between and span the grid elements 100 (shown in FIG. 4 and FIG. 5) and is supported by overlapping the lower portion of the grid element 100 in much the same way as a standard ceiling tile.
- the frame is of suitable strength to support a woven, or non-woven glass fiber, cloth, paper or plastic facing.
- An extrusion 302 can be secured to the frame element 300 and is of suitable strength to support a panel.
- the frame 300 is illustrated with the attached acoustical facing 308 .
- the frame 300 fits between the grid elements 100 and a suitable adhesive is applied to it to provide an attaching surface for the facing 308 .
- An extrusion 302 may be secured to the frame element 300 , upon which a suitable adhesive may also be applied to provide an attaching surface for the facing 308 .
- Other suitable mechanisms for attaching the facing 308 to the frame 300 may be used, such as mechanical fasteners.
- the attachment mechanism is preferably selected from those mechanisms capable of preventing the facing 308 from sagging.
- the decorative acoustic facing 308 may be a semitransparent covering applied to the frame element 300 .
- the acoustic facing 308 may be composed of glass fiber, cotton, imaged paper, imaged polypropylene or any woven, non-woven, or pressed material with sufficient acoustic transparency to enable efficient transfer of sound from a flat panel sound radiator or a standard speaker mounted in the frame element 300 .
- the facing 308 can be painted, stenciled or otherwise marked with any color or pattern so as to be substantially visually indistinguishable from surrounding ceiling panels.
- the embodiment illustrated in FIG. 3 includes a facing support 304 attached to the frame element 300 , which fits between the grid elements 100 .
- the facing support 304 further stabilizes the facing 308 by preventing the facing 308 from sagging.
- the facing 308 is fastened to the frame element 300 , extrusion 302 , and facing support member 304 with a suitable adhesive or other fastening method and spans the opening defined by the frame element 300 .
- the facing 308 can be painted, stenciled or otherwise marked with any color or pattern so as to be visually indistinguishable from surrounding ceiling panels in the suspended ceiling.
- the embodiment illustrated in FIG. 4 includes a flat panel sound radiator within the ceiling grid support elements 100 surrounding the location of installation.
- the grid elements 100 comprise part of the supporting structure for the suspended ceiling support system.
- the supporting grid elements are arranged in roughly the same size as the panel to be installed. Sufficient space is provided between the grid elements to allow the panel to be inserted and rest between them without falling through.
- An acoustic transducer assembly 408 provides mechanical power to the radiating panel 402 and is mounted on the back of the radiator panel 402 .
- the bridge element 404 is attached to the frame element 410 , and provides a mounting structure for the electrical components.
- the frame element 410 is centered between the ceiling support elements 100 , and contains the radiating panel 402 that is attached to an acoustic transducer(s) 408 .
- the frame element 410 provides support for the radiating panel 402 . Additionally, multiple exciters or transducers 408 can be used.
- the acoustic facing 406 is a decorative covering that is applied directly to the radiating panel 402 .
- the decorative acoustic facing 406 can be formed of woven glass fiber, woven cotton, imaged paper, imaged polypropylene or any woven or pressed material with sufficiently low mass and internal damping to enable efficient transfer of sound from flat panel speaker elements 402 and 408 mounted in the frame element 410 . Additionally, any facing material with high airflow resistance characteristics, which could not normally be used as an acoustic facing, are readily applicable in this configuration.
- the facing material is fastened to the radiating panel 402 with a suitable adhesive and spans the opening defined by the grid support elements 100 .
- the facing material can be painted, stenciled or otherwise marked with any color or pattern so as to be substantially visually indistinguishable from other ceiling panels in the same plane.
- a decorative pattern is applied onto the surface of the flat panel speaker using an organic coating, such as paint.
